ECM should not provide stealth 'Mech ability to block an entire team from sensors:
(Technical Readout: 3050 Revised, pg 196)
"The Guardian emits a broad-band signal that interferes with all sonar, radar, UV, IR, and magscan sensors, thus protecting all units in a radius of up to 180 meters by projecting a "cloak" to its enemies. Enemy long-range sensors can find vehicles and 'Mechs within the curtain, but the Guardian obscures the reading and prevents identification. By the time the enemy enters visual range, sensors can sometimes override the jamming, but by this time most pilots rely on their own eyes to track the opposition."
(Total Warfare, pg 134): "The ECM does not affect other scanning or targeting devices such as TAG and targeting computers"
ECM should not make missile locks impossible:
(Total Warfare, pg 134): "ECM blocks the effects of Artemis IV fire control systems. Artemis-equipped launchers may still be fired as normal missiles through ECM." and "Missiles equipped to home in on an attached Narc pod lose the Cluster Hits Table bonus for that system if the pods themselves lie within the bubble. The Narc launcher itself is not affected by ECM."
The previous rules state that missile attacks occur as normal, just not augmented with guidance from their advanced systems. Under no rulesets does it say that standard Guardian ECM negates the effect of Streak missile systems.
In disrupt mode ECM should have the following abilities:
-Disrupt Beagle's ability to detect shut down 'Mechs (Total Warfare, pg 134)
"Active probes cannot penetrate the ECM's area of effect. The probing unit would notice it is being jammed, however"
-Negate the tight groupings of Artemis-enhanced missiles (Total Warfare, pg 134)
"ECM blocks the effects of Artemis IV fire control systems. Artemis-equipped launchers may be fired as normal missiles through the ECM, but they lose the Cluster Hits Table Bonus"
-Negate the tight groupings of Narc-enhanced missiles, as well as prevent indirect fire on a Narc'd 'Mech without LOS (more on this later)
(Total Warfare, pg 134): "Missiles equipped to home in on an attached Narc pod lose the Cluster Hits Table bonus for that system if the pods themselves lie within the bubble. The Narc launcher itself is not affected by ECM."
-Prevent spotters in the ECM bubble, or on the other side of, with line of sight passing through a bubble from transmitting target data to team mates outside the bubble
(Total Warfare, Pg 134) "ECM has the effect of cutting off any C3 equipped unit from its network." Even though we don't officially have C3 installed on our 'Mechs, the way that our units communicate target data is what the C3 network does effectively. Being inside the ECM bubble should disrupt your ability to send data back to the rest of your team.
-Make target ID slower to acquire, but not block locks or targeting completely
(Maximum Tech, pg 54) "Though ECM systems can prevent a sensor probe from identifying a unit, they produce powerful distinctive electronic signatures."
(Technical Readout 3050: Revised, pg 196) "Enemy long-range sensors can find vehicles and 'Mechs within the curtain, but the Guardian obscures the reading and prevents identification."
So sensors know something is out there, it just can't identify it or provide target information like the paper doll.
-Generate ghost targets in a seperate mode from disrupt/counter - bring up the command map with B in ghost target mode and plot a false radar signal that shows up like a target shrouded by ECM - target-able by R, but no target data available
(Tactical Operations, pg 100): "The ECM suite can be tuned to generate "ghost targets" that may affect the ability of enemy units to properly target friendly units. The ECM loses its normal function when used this way."
-Run counter ECM mode
(Tactical Operations, pg 99): "An ECM suite can be tuned to act as electronic counter-countermeasures (ECCM) in order to negate enemy ECM systems."
Beagle should:
-Provide 360 degree scanning and targeting within a 150 meter bubble, including 'Mechs outside of line of sight such as behind buildings or terrain, as long as the 'Mech is not shut down
(Total Warfare, pg 129): "An active probe can detect any hidden 'Mech if the concealed unit lies within the probe's range." Like ECM, Beagle projects a scanning bubble of 5 hexes around it, equating to 150m of range
-Detect shutdown 'Mechs outside of ECM bubbles, if the unit with Active Probe has line of sight to the shut down unit
(Total Warfare, pg 129): "An active probe can detect any hidden 'Mech if the concealed unit lies within the probe's range."
-Negate ECM's target acquisition slowdown while outside the bubble
(Tactical Operations, Pg 99) "A unit with an active probe can also acquire information about an enemy unit’s status"
-Identify ECM Ghost targets as being false targets
(Tactical Operations, Pg 99) "A unit with an active probe will find it easier to overcome an ECM’s ghost target ability"
-Identify users the boundaries of the ECM bubble if they encounter ECM within Beagle's 150m scan bubble
(Total Warfare, pg 134)
"Active probes cannot penetrate the ECM's area of effect. The probing unit would notice it is being jammed, however"
The Narc beacon was rendered completely worthless when PGI failed to include its most important perk (Total Warfare, pg 139) which states:
"Once a Narc pod is attached to a target, all Narc-equipped missiles may be fired indirectly at a target without a spotter"
By this writing, we should be able to maintain locks on targets affected by Narc even if they go behind terrain and cut off line of sight, thus Narc should:
-Tighten LRM/SRM grouping on targets in line of sight
-Allow targets marked by Narc to remain targeted even when LOS is lost so LRM attacks can continue indirectly without spotters
-Last for either an extended duration than current or until the location the Narc hit is destroyed
A couple simple changes would make all of the advanced EW equipment viable, while remaining faithful to the source material without being game breaking or overpowering. ECM would still be useful to take, especially for protection against LRM spotters, as it would prevent them from sending target data to their LRM boats, protect you from Narc which would actually be a useful item if it kept enemies lit up on radar for indirect fire without a spotter like the rules say it does, and give Beagle expanded roles like countering ECM outside of the bubble (inspired by detection rules from MaxTech and Tactical Operations), and serving as a warning system that you are inside the bubble propper, which would be useful for spotters trying to Narc targets or transmit data.
The above changes would make information warfare have counters to each other, beyond just ECM, ECM, ECM. It would make it everything a useful addition to a team, but not an absolute necessity or gamebreaker.
